I had played this game quite a lot, until I found EvE Online. If you want to get away from EvE Online for a while, then this game may have what you are looking for.

It has many great features, and graphically it can still hold it's own against many modern games. I have never before seen an asteroid field dealt with so effectivley as this game. They are massive and very densely polpulated by 'roids.' The weapon effects are cool too as are the ships themselves which have retro thrusters all over their sufaces to control attitude, yaw and roll (a feature I'd wish they'd employ within EvE Online). Played with very much the same sort of mechanic as EvE Online, shields, armour, hull and utilising weapons such as lasers, missiles and ECM, Nexus - The Jupiter Incident is worth a look.
